Title: Fixing device
Inventor: TANAKA SHINICHI
IPC: G03G15/00
Filed: 1992-11-13
Abstract: PURPOSE:To substantially prevent the adhesion of toners to a heat roller and to prevent the offset of the toners to the heat roller by electrostatically charging the heat roller to the same polarity as the polarity of the toners. CONSTITUTION:A photosensitive drum 35 is electrostatically charged negative and the toners have a positive charge. Paper is electrostatically charged negative by a transfer roller 40. A fixing and transporting device 16 has the heat roller 50 internally having a heater 50a and a press roller 51 which can come into pressurized contact with the heat roller 50. The surface of the heat roller 50 is coated with a nonconductive PTFE resin. Electron-donating materials, such as ligrosine dyes, fatty acid metal salts and quaternary ammonium salt, are incorporated as charge control agents into the PTFE resin. As a result, the surface of the heat roller 50 is electrostatically charged positive by friction with a cleaning member. Then, the adhesion of the toners to the heat roller 50 is substantially prevented by the electrical repulsive force between the toners and the heat roller 50 surface.

Title: Roaster
Inventor: OYABU YASUNORI
IPC: F23N5/08
Filed: 1988-11-30
Abstract: PURPOSE:To execute proper heat cooking easily by comparing an output of a smoke detecting means with a reference value set beforehand and by controlling heating of foodstuff on the basis of a time elapsing from the time when the output reaches some prescribed value. CONSTITUTION:Foodstuff is heated, a scorched part begins to appear with the rise in temperature, and smoke 12 reaches the position of a smoke detecting element 1 from a heating chamber through a groove 7 or the like. The smoke scatters light 11 emitted from a light-emitting element 10, scattered light 13 is formed thereby, and by measuring the quantity of the scattered light 13, the smoke 12 can be detected as the density of an ambience. The result of this detection is transmitted to a control element 2. The control element 2 judges a time point when an output of the smoke detecting element 1 reaches a very low set amount, as the time point when the scorched part begins to appear on the foodstuff, and the extent and state of the scorched part on the foodstuff are adjusted on the basis of the length of a time elapsing from the time point. A light-sensing element 14 converts the quantity of the scattered light into the amount of a current and this amount is set to be the voltage across a third resistance 17. When the voltage across the resistance 17 exceeds a voltage corresponding to the set amount of the density of the smoke, a timer 19 starts to operate. The time counted by the timer 19 reaches a set value, and thus heat cooking is completed.

Further, because the rollers 17 are rolled on the roller rolling face 12b of the fixed member 11, smooth movement of the movable member 13 can be guaranteed.

Title: Production of aromatic fluorine compound
Inventor: HARADA ISAO
IPC: C07B39/00
Filed: 1989-11-27
Abstract: PURPOSE:To obtain the subject substance in high yield by reacting an aromatic amino compound with a nitrous acid imparting agent in the presence of hydrofluoric acid, preserving the resultant diazonium salt at a specific low temperature and then thermally decomposing the diazonium salt. CONSTITUTION:An aromatic amino compound (e.g. aniline or toluidine) is reacted with a nitrous acid imparting agent in the presence of hydrofluoric acid at -40 to +10 deg.C to form a diazonium salt, which is then preserved at <=-10 deg.C (preferably at -40 to -10 deg.C) and further thermally decomposed at 30-80 deg.C to afford the subject substance. Treatments, e.g. sealing of an inert gas in a container are preferably carried out so as to prevent the diazonium salt from contacting the outside air. No change is observed in diazotization ratio of the diazonium salt preserved at <=-10 deg.C even after the lapse of several days and the yield of the aromatic fluorine compound after completing the subsequent thermal decomposition is also excellent.
